However, there are other words that can be used to describe this type of machine. One alternative is "automated vendor," which emphasizes the machine's ability to operate without human intervention. Another option is "dispenser," which can be used to describe any machine that dispenses products or services. "Snack machine," "soda machine," and "coin-operated machine" are other words that can be used to describe vending machines, depending on the products they dispense or the payment method they accept.
